The

spout provides. an opening, l9leading to the inte-f rior 'of thecontainer and by means oi which the .contents thereof may bedispensedg; Forjconvenience indispensing the liquid within the. con 7 mtainer the spout ispositioned on thetop portion at agslight inclinationwith respect to a'horizontal v ew taken substantially The-spout Ii provided'wi-th a coverindicated V in'its entirety by M and'which cover has a hinge portion l6 pivotally connecting; by means. of a stud or'pivot shaft ill, with bifurcated ears l8 extending rearwardly from the spout. As a re.-

suit of the hinged connection of the cover to the spout the cover may oscillate from a closedposi: tionto an open position. This latter position is shown in Figure 1.] When the coveris closedon the spout it willbeunderstood that the contents 7 of the container are sealed from the atmosphere. The stud l.1 frfhinging. the cover is best shown inFigure 2, wherein it will be observed that said stud passes through both of the ears I8 and spouts with a pouring lip indicated. by numeral 3.0, Figure 1. Said pouring lip is located on the spout l I at some distance below the fl-a't top surface 25 so thatthe lip will notint'erfere with the cover l4 when said cover is. in closed position on the. spout. Also it will be observed that the pouring lipmay becast integrai'with'the spout.

(and. accordingly manuiacturinggcosts are not materially increased? Although theli p may be as a separate unit and weld the lip to the cylinthrough the hinge portion IQ of the cover. on "Z having encircling relation with'the stud are coil springs 20. The coil springs are providedfior yieldingly forcing the cover into'a nosed position on thespout.
